I love the lemon smell. This shampoo cleans my oily scalp/hair like no other. I have to wash my hair every day, and I have noticed that daily use of this shampoo makes my scalp too dry and a bit flaky. That's why I'm using it every other day, alternating with softer regular shampoos for daily use. My sister and my dad like it too and have started using it. Also, a little bit goes a long way. Very good product.
Update (3/29/12): It seems that the formula for this shampoo has been changed. The stuff in the newer bottles is much less concentrated than before, which means that it now takes twice the amount of shampoo to work up a good lather. A little doesn't go a long way any more. Also, the strong lemony smell is gone. Too bad.

I've tried all but one of the shampoo-conditioner sets in this product line, and am impressed by all of them. They are the only ones I've found that have no version of sulfates, and really manage my ultra-fine hair well. For my hair, the Italian Grape is best, but I use the Lemon in summer so that insects don't mistake me for fruit salad.

I almost ruined my hair using this product. I bought it thinking it would be a good shampoo to remove residue from hair products I use. It might be okay to use this occasionally, but it should never be used on a regular basis, as it strips the hair of everything including moisture. It took me months to get my hair back to a healthy condition.
